What is the value of k for which the following equation has one solution?|14+ 7x| - 15 = k
1 answer:
Answer:
7x-1
Step-by-step explanation:
14 + 7x - 15 = k
7x - 1 = k
Finding x,
14 + 7x - 15 = k
=> 14 + 7x = k + 15
=> 7x = k + 15 - 14
=> x = (k + 1)/7
So, 7 * (k+1)/7 - 1 = k
k + 1 - 1 = k
=> k = k
So the answer is true that 7x - 1
